Frequently Asked Questions
We design and manufacture metallic expansion joints (axial, lateral, universal/tied, hinged, gimbal, pressure balanced inline & elbow, externally pressurized), rectangular bellows, rubber & fabric/duct expansion joints, exhaust/engine bellows, PTFE‑lined joints, and flexible metal hose assemblies with end fittings.
Yes. We engineer custom sizes, ply combinations, convolution profiles, tie‑rod/hinge/gimbal hardware, liners, covers and end connections to match your pressure, temperature, movement and space constraints. Share line size, design pressure/temperature, movement (axial/lateral/angular), and end type for a fast quote.
Common bellows materials include SS304/304L, SS316/316L; on request we can build in higher‑alloy steels or nickel‑based grades for demanding media/temperatures. End fittings, flanges and hardware are matched to service and standards. Rubber/fabric joints use reinforced elastomers and high‑temp fabrics as per duty.
Match the joint to the predominant movement and system layout: axial (axial bellows, externally pressurized), lateral (lateral/universal tied), angular (hinged/gimbal), or combined (pressure balanced for minimal anchor loads; rectangular for ducts). We’ll validate movements, spring rates and anchor loads from your piping data.
Each assembly undergoes dimensional checks and pressure tests (typically hydro or pneumatic as applicable). Welds are qualified to procedure, and accessories (liners, covers, tie rods, hinges, gimbals) are verified for travel and stops. Test certificates and inspection records can be supplied with dispatch.
Yes. For custom items we share GA/approval drawings indicating overall length, convolution geometry, end type, hardware, movements, spring rates and test details before fabrication.
Standard sizes are often dispatched quickly; custom designs depend on size, material and hardware. Share your required date—our team will confirm the build schedule. We accept single‑piece orders for most custom bellows.
Yes—installation guides are provided. Key points: keep the bellows neutral at fit‑up, align piping, support loads properly, remove shipping bars only after installation, and do not use bellows to correct misalignment. We can advise on anchors, guides and cold‑spring if needed.
Absolutely. Send dimensions (overall length, live length, OD/ID), end type, movement and service data—or share the old part for reverse engineering—and we will supply a drop‑in replacement or an upgraded design.
Line size & end connection, design pressure/temperature, medium, required movements (axial/lateral/angular), available face‑to‑face length, hardware (tied/hinged/gimbal/liners/covers), quantity and delivery location. Drawings/photos help accelerate engineering.
Service life depends on movement cycles, temperature, pressure and alignment. Ensure proper guiding/anchoring, avoid torsion, protect from external damage, and inspect periodically for leaks or deformation. Adding liners/covers can improve life in abrasive or high‑velocity flow.
Yes, we ship across India and internationally through dependable logistics partners. Packaging is engineered to protect convolutions and hardware in transit.
